A Study of Water Modelling on Mechanism of Removal of Inclusions in Molten Steel by Bubble Wake
Teshugang, 2014 The removing process of inclusions by bubble wake in steel has been studied by using water model and high-speed video recorder and the rule of inclusions removing through bubble wake and the effect of bubble size and inclusion size and concentration on ...

Bubble, Bubble, Where's the Housing Bubble? [PDF]
Discussions of whether a housing bubble exists generally rely on indirect barometers such as rapidly increasing prices, unrealistic expectations of future price increases, and rising ratios of housing price indexes to indexes of household income.

Prediction of bubble size in Bubble columns using Artificial Neural Network
Iraqi Journal of Chemical and Petroleum Engineering, 2009 In the literature, several correlations have been proposed for bubble size prediction in bubble columns. However these correlations fail to predict bubble diameter over a wide range of conditions. Based on a data bank of around 230 measurements collected
